Kafka for Developers - Data Contracts Using Schema Registry - What's Inside an AVRO Record?

This lecture covers the internals of Avro serialization and deserialization, focusing on how data and schema are transmitted together in Kafka. It highlights the challenges of bulky messages and inefficient network usage due to schema transmission. The lecture introduces the Schema Registry as a solution, which allows sending schema IDs instead of full schemas, reducing message size and improving efficiency. A practical example demonstrates the impact of schema on message size, and the lecture concludes with a preview of future topics.
